DERAILING-SWITCH.

Specification of' Letters Patent.

Patented 001'. 15, 1907.

Application iiled March 18.1907. Serial No. 362,966.

To all whom it may concern:

Be it known that we, LEROY J. LiNDsAY and .Iosnrn H. CARROLL, citizens of the United States, residing at Seymour, in the county of Wayne and State of Iowa, have invented a certain new and useful Derailing- Switch, of which the following is a specification.

The object of our invention is to provide a derailing switch of simple, durable and inexpensive construction so arranged that when in position lor use, it will rest firmly upon the rail and be held against movement laterally' in either direction and when a car wheel approaches it both the wheel tread and the wheel flange will rest upon the derailing switch and be directed to the outer side ofthe rail, thus avoiding danger' of breaking the flange of the wheel and when the derailing switch is in its position out of use, it will stand wholly outside of the rails and out of contact therewith.

A further object is to provide a switch operating device of simple, durable and inexpensive construction that may be operated to move the switch proper from one position to another easily and quickly and with a minimum of applied power.

Our invention consists of certain details in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter' more fully set forth, pointed out in oru claims and illustrated in the accompanying drawings, in whichi Figure l shows a plan view of a railway rail and our improved derailing switch applied thereto and shown in its position for use.V Fig. 2 shows a sectional View on the line 2-2 of Fig. l. Fig. 3 shows a similar view with the switch in its position away from the rail, and Fig. 4 shows a perspective view of the derailing plate resting on a rail. I

Referring to the accompanying drawings, I have used the reference numeral l0 to indicate the track rail and Il the crossties.

The derailing switch plate is preferably formed complete of asingle piece of metal and is designed to lie flat on top of the rail l0. In its top is a diagonal groove l2 extending from a point at one end adjacent to the inner edge of the rail top to a point at its other end beyond the outer edge of the rail top. At the Outer side of the groove l2 is the guide rib I3 and at the inner side is the guide rib 14. The ends of both of these ribs that are directly over the rail are beveled to a thin edge adjacent to the top of the rib. Formed in the rib 14 is a groove l5 so arranged as to receive the flange of a rail plate is a downwardly projecting flange IG designed to prevent the derailing plate from moving outwardly off of the rail without first being elevated. We have provided a rigid support I7 fixed to the cross ties to engage and support said flange 17. Fixed to the outer edge of the derailing plate is a bar I8 projected downwardly below the top of the rail to prevent the derailing plate from-moving inwardly off of the rail without first being elevated. By means of the flange 16 and the bar IS, the derailing plate will be firmly and securely held upon the top of the rail against movement either inwardly or' outwardly without first raising the plate above the rail and on account of the shape of the ribs and grooves in the top of the derailing plate a car wheel approaching it from the left to the right will be raised above the rail, the tread portion of the wheel resting upon the rib 13 and the iiange of the wheel resting in the groove I2 and the wheel will be carried thereby over the rail and be directed off ofthe rail at the end of the derailing plate. By thus having both the flange and the tread of the wheel supported by the derailing plate, we avoid danger of breaking the wheel flange during the process of derailing the wheel.

le have provided for operating the derailing plate as follows: Mounted upon one of the cross ties is a bellcrank lever 19. Pivoted in one end of this bellcrank lever is a link 20 extended in a direction toward the rail 1). Pivoted to the said link 20 is a derailing plate supporting frame 2l fixed to the derailing plate. Pivoted between the sides of the frame 2l is a lever 22 having parallel sides which are pivoted to a rod 23, which rod is detachably supported in the brackets 24 on top of the adjacent cross ties. The shape of the lever 22 is such that when the bell-crank lever 19 is adjusted from the position, shown in Fig. I, to its other limit of movement, the derailing plate supporting frame 2l will be first moved in a direction causing the derailing plate to be elevated above the rail and then moved outwardly over the rail and then downwardly to the position shown in Fig. 3, or it will be supported out of contact with the rail and when the bell-crank lever I9 is moved in the opposite direction, the derailing plate will be moved toward the rail and elevated over it and then lowered to the position shown in Fig. 2. By rising the link 20 to connect the bell-crank lever with the frame 2l, we avoid all binding strains upon the bearings of said frame and the operation of the derailing plate from one position to another is made very easy.

Having thus described our invention, what we claim and desire to secure by Letters Patent of the United States, therefor isA I 1. In a derailing switch, the combination of a derailing' plate designed to rest on top of a rail, and provided with a diagonally arranged groove to engage a wheel ange, and cause the Wheel to move over' the rail to the outer' side thereof, a supporting frame fixed to the plate, and extended outwardly therefrom,rneans attached to the outer end of the supporting frame for moving it toward and from the rail, and a lever fulcrumedto a stationary support between the rail and the outer end of the frame, and pivotally connected with the said frame between its ends, said levers so shaped and proportioned that when the supporting frame is moved away' from a rail, the derailing plate will trst be elevated and then moved to a position spaced apart from the rail.

2. In a device of the class described, a derailing plate designed to rest on top' of a railway rail and having anges at its sides to project downwardly along the sides of the rail and having in its top a diagonal groove to receive the flange of the rail, a raised rib havinga beveled end to receive the tread portion of a wheel and cause it to move from the top of the rail upwardly across the dei-ailing plate to the outer edge of the rail, and a rib on the other side of the groove, said rib provided with agroove designed to direct a wheel flange upwardly 'over the rib and into the said diagonal groove to prevent said wheel from becoming derailed.

3. In a device of the class described, a derailingplate designed to rest on top of a railway7 rail and having a di agonal groove therein, a rib at one side of said groove having a beveled portion projecting beyond the groove to the top of a rail and also having a rib at the other side of the groove projecting beyond the groove and extending to the top of the rail, said latter rib having a groove therein inclined from the bottom of the plate to the top of the rib adjacent to the said diagonal groove, the diagonal groove and the rst-lnentioned rib shaped to derail a wheel passing over the plate in one direction and the other rib and groove designed to carry a Wheel over the derailing plate without derailing it.

4. In a device of the class described, the combination of a derailin'g plate having flanges projecting below the stationary supports to receive the inner ange when the plate is resting` on a rail, a supporting frame fixed to the plate and extended outwardly'therefrom, a link pivoted to the outer end of the supporting frame, a bellcrank lever connected with said link and a lever fulcrulned to a stationary support and pivotally connected with the supporting lframe, said lever so shaped and proportioned that when the supporting frame is moved away from a rail the derailing pflatewill rst be elevated so that its iianges clear the rail.
